This program simplifies the youtube-dl application by rg3, and gives it a user friendly interface for downloading from websites.

When you first run this program, it'll ask for a directory to store downloaded files. Select your desired location and then set it. Afterwards, you can configure settings if you'd like or just straight up start downloading.

Downloading with custom formats and converting in any way will require FFmpeg, which you can download and put the "ffmpeg/bin/*.exe" files with the same directory as youtube-dl-gui or extract it anywhere and put the bin directory into your windows PATH.
